You could pot them together but keep them in separate pots. You can put the pots in a larger container and cover the whole thing with some bark or sphag. Makes a pretty arrangement.

Keeping them separate makes it easier to deal with problems which could arise. If they are all planted in one pot and you have a problem, it is hard to treat one plant without affecting the other. All the roots would intermingle and make it hard to remove one.

Either way, you can wait to repot until spring when whether warms and your blooms should be finished.
